Because of Elon Musk Twitter has been in the news for months. That includes his impulsive decision to buy it, firing massive amounts of people, and to keep everyone focused on him a barrage of right wing themed tweets about hot button political topics. Of course the news media is reporting on this.
Then a massive US tech company, whose founder has a hollywood blockbuster biopic, releases a clone of Twitter. That's also news.
THEN Elon Musk sues them right after the launch publically claiming former Twitter employees stole code. You know, Elon Musk, the person I mentioned who did all those things he what did.
Then you make this "oh typical US media, the Zucks has them under his liberal soft thumb" comment because no way the news would normally report on all these major public and outrageous figures along their big business infighting
